  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram showing an external appearance of a musical sound generating apparatus according to the first embodiment of the present invention. A musical sound generating apparatus 10 according to the present embodiment includes a switch unit 11 in which various switches are arranged on the lower side, a display unit 12 including a large liquid crystal display device, and a touch panel 13 arranged to overlap the display unit 12. And a speaker 14. In the musical sound generating apparatus 10 according to the present embodiment, when a player touches a note displayed on the screen of the display unit 12, the touch is detected by the touch panel 13 and the CPU 21, and a musical sound with a predetermined pitch is generated. It is supposed to be.

  FIG. 2 is a block diagram showing the configuration of the tone generation apparatus according to the present embodiment. As shown in FIG. 2, the musical sound generation apparatus 10 according to the present embodiment includes a CPU 21, ROM 22, RAM 23, flash memory 24, sound system 25, external I / F 28, switch unit 11, display unit 12, and touch panel 13. .

  The CPU 21 controls the entire musical sound generating device 10, detects the operation of the switches constituting the switch unit 11, detects the touch on the touch panel 13, controls the sound system 14 according to the touch on the touch panel 13, and the screen of the display unit 12 Various processes such as generation of musical score data to be displayed above and operation guide of the touch panel for the performer in the automatic performance mode are executed.

  The ROM 22 performs various processes to be executed by the CPU 21, for example, control of the entire tone generator 10, detection of operation of the switches constituting the switch unit 11, detection of contact with the touch panel 13, and sound according to contact with the touch panel 13. Programs such as control of the system 14, generation of musical score data to be displayed on the screen of the display unit 12, and a touch panel operation guide for performers in the automatic performance mode are stored. The ROM 22 has a waveform data area that stores waveform data for generating musical sounds such as piano, guitar, bass drum, snare drum, and cymbal. The RAM 23 stores a program read from the ROM 22 and data generated in the course of processing. The flash memory 24 stores music data of various music pieces and automatic accompaniment data of the music pieces.

  The sound system 25 includes a sound source unit 26, an audio circuit 27, and a speaker 14. When the sound source unit 26 receives, for example, a note-on event based on touch on the touch panel from the CPU 21, the sound source unit 26 reads predetermined waveform data from the waveform data area of the ROM 22, generates musical tone data of a predetermined pitch, and outputs it. The sound source unit 26 can also output waveform data, particularly waveform data of percussion instrument sounds such as a snare drum, bass drum, and cymbal, as musical sound data. The audio circuit 27 D / A converts and amplifies the musical sound data. Thereby, an acoustic signal is output from the speaker 14.

  The external I / F 28 has a memory card slot, can accept a memory card (not shown), read data from the memory card, or write data to the memory card. The external I / F 28 also includes a communication means for realizing connection with an external network such as the Internet, and realizes data transmission / reception with other devices via the external network. In addition, the musical tone generation apparatus 10 according to the present embodiment generates a musical tone having a predetermined pitch based on the touch on the touch panel 13 in both the normal mode and the automatic performance mode.

  Hereinafter, the process performed in the musical sound generating apparatus 10 according to the present embodiment will be described in more detail. FIG. 3 is a flowchart illustrating an outline of processing executed in the musical sound generation apparatus according to this embodiment. When the tone generator 10 is turned on, the CPU 21 of the tone generator 10 executes an initial process (initialization process) including clearing the data in the RAM 23 and the display screen of the display unit 12 (step 301). .

  When the initial process (step 301) ends, the CPU 21 detects each operation of the switches constituting the input unit 11, and executes a switch process for executing a process according to the detected operation (step 302). FIG. 4 is a flowchart illustrating an example of the switch processing according to the present embodiment. As shown in FIG. 4, the switch processing includes song selection processing (step 401), mode selection processing (step 402), start / stop switch processing (step 403), tone selection processing (step 404), and other switch processing. (Step 405) is included.

  FIG. 5 is a flowchart showing an example of song selection processing according to the present embodiment. As shown in FIG. 5, the CPU 21 determines whether the song button in the input unit 11 is turned on (step 501). If it is determined NO in step 501, the song selection process is terminated. If it is determined Yes in step 501, the CPU 21 acquires the title (song name) of the song data from the flash memory 24 and displays a list of song names (song list) on the screen of the display unit 12. . Further, the CPU 21 highlights the song name corresponding to the cursor position in accordance with the operation of the cursor button in the input unit 11 by the performer (step 502).

  The CPU 21 determines whether the determination switch in the input unit 11 is turned on (step 503). If “No” is determined in step 503, the process returns to step 502. If it is determined Yes in step 503, the CPU 21 reads a predetermined number of records of the song data with the song name at the cursor position from the start address of the song data (step 504).

  FIG. 6A is a diagram illustrating a configuration example of song data according to the present embodiment. As shown in FIG. 6A, the song data 600 according to this embodiment includes a note-on event record (see reference numeral 601), a time record (see reference numeral 602), and a note-off event record (see reference numeral 603). ) And a time record (see reference numeral 604).

  The record of the note-on event includes information indicating the tone color and pitch of the tone to be generated. The value stored in the time record that follows the record of the note-on event is the time interval between the note-on event and the note-off event for the note-on event. Indicates the sound length. Therefore, the note position and note type in the staff can be specified by the pitch information in the note-on event and the value (sound length) in the record of the continuation time.

  The record of the note-off event includes information indicating the pitch of the musical sound to be muted. The value stored in the time record following the note-off event record indicates the time interval between the note-off event and the next note-on event. Therefore, the value of the time record following the note-off event can specify the type of rest between adjacent notes arranged in the staff.

  In step 504, the CPU 21 may read a record of music data corresponding to a predetermined number of bars from the first bar in order to be initially displayed on the screen of the display unit 12. Next, the CPU 21 generates note data including the note position and note type based on the note-on event and the next gate time in the record of the read music data (step 505). In addition, rest data based on the gate time and the next step time is also generated in step 505.

  Next, the CPU 21 generates image data in which notes and rest symbols according to the note data and rest data generated in step 505 are arranged in the staff (step 506). Further, the CPU 21 generates a cursor in the image that points to the first note (step 507). In the present embodiment, a cursor placed at the top of a note is used as a note indicator indicating a note to be touched by a performer with a finger. The CPU 21 stores the position information (coordinates) of each note and rest in the image in the RAM 23 (step 508). Further, the CPU 21 stores the address (for example, the final address) of the song data record corresponding to the note and rest displayed on the screen of the display unit 12 in the RAM 23 as the address DAD (step 509). FIG. 6B is a diagram illustrating an example of the score displayed on the screen 610 of the display unit 12 in this way. In the example of FIG. 6B, the cursor 612 points to the first note (symbol 611).

  In a mode selection process (step 402) executed subsequent to the song selection process (step 401), the CPU 21 selects a performance mode by a mode selection button in the input unit 11, and information MODE indicating the performance mode is stored in the RAM 23. Stored inside. More specifically, in the present embodiment, the player touches the note to be turned on in the normal mode (MODE = 0) in which guidance using automatic performance is not performed and the mode in which automatic performance is performed. The first automatic performance mode (MODE = 1) in which the automatic performance does not proceed unless there is no, and the second automatic performance mode (MODE = 2) in which the automatic performance proceeds regardless of whether the player's note is on, Information indicating any performance mode is stored in the RAM 23.

  Following the mode selection process (step 402), the CPU 21 executes a start / stop switch process (step 403). FIG. 7 is a flowchart showing an example of start / stop switch processing according to the present embodiment. As shown in FIG. 7, the CPU 21 selects the automatic performance mode (first automatic performance mode: MODE = 1 or second automatic performance mode: MODE = 2) as the performance mode selected by the mode selection process. It is determined whether it exists (step 701). If it is determined No in step 701, that is, if the performance mode is the normal mode (MODE = 0), the start / stop switch process is terminated. If it is determined Yes in step 701, the CPU 21 determines whether or not the start / stop switch in the input unit 11 has been operated (step 702). If it is determined No in step 702, the start / stop switch process is terminated.

  If it is determined Yes in step 702, the CPU 21 inverts the start flag STF stored in the RAM 23 (step 703), and determines whether the start flag STF is “1” (step 704). If it is determined Yes in step 704, the CPU 21 obtains the start address of the record of the song data of the selected song (step 705). The CPU 21 stores the acquired head address in the RAM 23 as a parameter AD indicating the address (step 706).

  The CPU 21 reads the record of the music data G (AD) indicated by the head address AD, and stores the record value as the timer register value T (step 707). Further, the CPU 21 advances the parameter AD indicating the address (step 708).

  Further, the CPU 21 cancels the timer interrupt (step 709). By canceling the timer interrupt, a timer interrupt process is executed at a predetermined time interval, and a timer provided in the CPU 21 is incremented. If NO is determined in step 704, that is, if the STF is “0”, the CPU 21 stops the timer interrupt (step 710).

  Subsequent to the start / stop switch process (step 403), the CPU 21 executes a tone color selection process (step 404). In the timbre selection process, the timbre information of the tone selected by the player's operation of the timbre selection switch (tone switch) of the switch unit 11 is stored in the RAM 23. After the timbre selection process (step 404), the CPU 21 executes another switch process (step 405). Other switch processing includes setting tempo data by operating the tempo switch and storing the tempo data in the RAM 23.

  When the switch process (step 302) ends, the CPU 21 executes a panel operation detection process (step 303). 8 to 10 are flowcharts showing an example of panel operation detection processing according to the present embodiment. CPU21 detects the operation state to the touch panel by a player (step 801).

  If the operation state on the touch panel is “none”, that is, the state where the performer's finger is not touched on the touch panel is continued, the panel operation detection process ends. The case where the performer's finger is newly turned off (new off) will be described later. When the performer's finger is touched on the touch panel (ON), the CPU 21 determines whether the performer's finger is touched on the touch panel (new ON) (step 802).

  If Yes in step 802, that is, if it is new on, the CPU 21 determines whether or not the position touched by the performer with the finger corresponds to the peripheral area of the note displayed on the screen. FIG. 11 is a diagram illustrating an example of a peripheral region according to the present embodiment. In FIG. 11, a staff (reference numeral 1110) and a quarter note (reference numeral 1100) having a pitch of C4 are arranged on the screen of the display unit 12. In the present embodiment, the first region (a region) and the second radius (> first region) are within a predetermined first radius range (see reference numeral 1101) from the position where the note 1100 is arranged. The area excluding the first area within the radius range (see reference numeral 1102) is defined as a second area (b area). Furthermore, in the second area (b area), an area whose Y coordinate is smaller than the Y coordinate of the note position is a b-area (see reference numeral 1103), and the Y coordinate is the Y coordinate of the note position. The region as described above is defined as a b + region (see reference numeral 1104).

  In the present embodiment, basically, when the performer's finger is in the first region (region a), a musical tone having a pitch corresponding to a note is generated. When the performer's finger is in the b-region, a musical tone having a pitch that is a semitone below the pitch corresponding to the note is generated, and when the performer's finger is in the b + region, A tone that is a semitone above the corresponding pitch is produced. These first region (a region) and second region (b region) are collectively referred to as a peripheral region.

  In the musical score displayed on the screen of the display unit 12, the peripheral area may be displayed around the note or may not be displayed. Further, when the peripheral area is displayed, the first area and the second area may be displayed, respectively, or only the second area that defines the outline of the peripheral area may be displayed.

  In step 803, the CPU 21 specifies the peripheral area where the finger is located based on the position of the finger newly turned on by the performer and the peripheral area of the note displayed on the screen of the display unit 12 (step 803). 803). As will be described later with reference to FIG. 15 and the like, there are cases in which the peripheral areas of a plurality of notes overlap. In this case, the CPU 21 prioritizes a note that precedes in time in the music (that is, a note located on the left side of the score) and identifies the peripheral area. The CPU 21 determines whether the position of the finger is within the peripheral area of any note (step 804). If it is determined No in step 804, the panel operation detection process is terminated. On the other hand, if it is determined Yes in step 804, the CPU 21 executes a sound generation process according to the type of the peripheral area (step 805). In the sound generation process, a note-on event including the pitch and tone color information of the tone to be generated is generated.

  In the example shown in FIG. 11, when the performer's finger is newly turned on in the first area (area a) 1101, the CPU 21 presets the pitch (C4) indicated by the note. The note-on event including the timbre information thus generated is generated, and the note-on event is output to the sound source unit 26. When the player's finger is newly turned on in the b + region 1104 of the second region (b region) or newly turned on in the b− region 1103, Each includes a note-on event including a pitch (C # 4) that is a semitone above the pitch indicated by the note and timbre information, or a pitch (B3) that is a semitone below the pitch indicated by the note and the timbre information. A note-on event is generated and output to the sound source unit 26.

  After step 805, the CPU 21 sets the pronunciation status to “sounding” for the musical tone of the pitch for which the note-on event is generated in the RAM 23 (step 806). Further, the CPU 21 determines whether or not the start flag STF is “1” (step 807). If it is determined Yes in step 807, the CPU 21 executes a guide determination process (step 808). The guide determination process will be described later.

  On the other hand, when it is determined in step 801 that “new off”, the CPU 21 determines whether or not the sound generation status in the RAM 23 is sounding (step 809). If it is determined No in step 809, the panel operation detection process ends. If it is determined as Yes in step 809, the CPU 21 generates a note-off event for the musical sound whose pronunciation status is “sounding” and outputs it to the sound source unit 26 (step 810). Next, the CPU 21 changes the sounding status that was “sounding” to “mute” (step 811).

  FIG. 12A is a diagram illustrating an example in which the performer touches the finger on the touch panel and moves the finger in that state, and then the finger is separated from the touch panel. In FIG. 12A, a black dot at one end of a line with an arrow indicates a position newly touched on the touch panel, and a tip of the arrow indicates a position separated on the touch panel. For example, in the example of the line 1201, the performer's finger is newly turned on in the first area, moved in contact with the first area, and is also newly turned off in the first area. . Therefore, a note-on event including the pitch C4 is generated with the new on, and a note-off event with the pitch C4 is generated with the new off.

  In the example shown by the line 1102, the performer's finger is newly turned on in the b-region and is also newly turned off in the b-region. Accordingly, a note-on event including the pitch B3 is generated with the new on, and a note-off event with the pitch B3 is generated with the new off. Furthermore, in the example shown by the line 1203, the player's finger is not located in the peripheral area of the note, so that a note-on event is not generated.

  On the other hand, as shown in FIG. 12B, the player's finger may be moved over a plurality of areas. For example, the following modes can be considered.

Newly turned on in the b-region, moved in the a region, and then turned off in the a region (reference numeral 1211).
Newly turned on in the b + region, moved in the region a, and then turned off in the region a (reference numeral 1212).
Newly turned on outside the peripheral region, moved to the b-region, and then turned off in the b-region (reference numeral 1213).
After turning on a new area outside the peripheral area and moving to the b-area, it further moves to the a area and turns off anew in the a area (reference numeral 1214).

  In addition to the above, there may be cases where a plurality of areas are covered. Therefore, the panel operation detection process according to the present embodiment can cope with the above-described movement of the player's finger. If NO in step 802, that is, if the performer is turning on his / her finger on the touch panel, the CPU 21 displays the position touched by the performer's finger on the screen as shown in FIG. It is determined whether it corresponds to the peripheral area for the note (step 901). Next, the CPU 21 determines whether the detected peripheral area is different from the peripheral area detected in the previous process, that is, whether the type of the peripheral area has been changed (step 902). Note that movement from the b− region to the b + region is also determined as a change in the peripheral region.

  If it is determined No in step 902, the panel operation detection process is terminated. If it is determined YES in step 902, the CPU 21 determines that the position of the performer's finger is in the peripheral area, that is, the first area (a area) or the second area (b− area or b + area). (Step 903). If it is determined Yes in step 903, the CPU 21 determines whether the sounding status stored in the RAM 23 is “sounding” (step 904). When it is determined Yes in step 904, the CPU 21 executes a pitch change process according to the type of the peripheral area where the finger is located (step 909).

  In the pitch change process, a note-off event for muting the musical tone of the pitch corresponding to the peripheral area before movement is generated and output to the sound source unit 26, and the pitch and tone corresponding to the peripheral area after movement are generated. A note-on event including information is generated and output to the sound source unit 26. Thereby, a musical tone having a pitch corresponding to the peripheral area after movement can be generated.

  In FIG. 12B, when a new on is performed in the b-region and moved in the a-region (reference numeral 1211), a new tone in the b-region generates a musical tone B3 that is a semitone below C4. By moving from the b-region to the a region, the pitch of the musical sound is changed to C4. In addition, when it is newly turned on in the b + region and moved in the region a (reference numeral 1212), a new tone in the b + region generates a C # 4 musical tone that is a semitone above C4, and from the b + region to the a region. By moving to, the pitch of the musical tone is changed to C4.

  If it is determined No in step 904, the CPU 21 executes a sound generation process according to the type of the peripheral area (step 905). In step 905, as in step 805 in FIG. 8, the CPU 21 generates a note-on event including pitch and timbre information corresponding to the surrounding area, and outputs it to the sound source unit 26. Further, the CPU 21 determines whether or not the start flag STF is “1” (step 906). If it is determined Yes in step 906, the CPU 21 executes a guide determination process (step 907). Thereafter, the CPU 21 sets the sound generation status to “sounding” for the musical tone of the pitch for which the note-on event is generated in the RAM 23 (step 908).

  In FIG. 12B, when it is newly turned on outside the peripheral region and moved to the b-region (refer to reference numeral 1213), by moving to the region b-, B3 that is a semitone lower than the pitch C4 of the note. Music is generated. In addition, when the signal is newly turned on outside the peripheral area, moved to the b-area, and further moved to the a-area (see reference numeral 1214), by moving to the area b-, the pitch C4 of the note is changed. A musical tone of B3, which is lower by a semitone, is generated, and the pitch is changed to C4 by moving to the a region.

  Next, the case where No is determined in step 903 will be described. In this case, the CPU 21 determines whether the sounding status stored in the RAM 23 is “sounding” (step 1001). If it is determined as Yes in step 1001, it means that the position of the performer's finger has moved from any of the surrounding areas to the outside of the surrounding area. Therefore, in this case, the CPU 21 executes a mute process (step 1002). In the mute process, the CPU 21 generates a note-off event for a musical tone whose sound generation status is “sounding”, and outputs it to the sound source unit 26.

  When it is determined No in step 1001 or after step 1002 is executed, the CPU 21 determines whether or not the position of the performer's finger is in the peripheral area for other notes (step 1003). 13 and 14 are diagrams showing an example in which a plurality of musical notes are arranged on the staff in the image on the screen of the display unit. In the example shown in FIG. 13, the peripheral areas of the two musical notes 1300 and 1310 do not overlap. That is, the second area of the note 1300 (see reference numeral 1301) and the second area of the note 1310 (see reference numeral 1311) are separated from each other. Therefore, when the performer's finger is turned on in the first area (area a) of the note 1300 and goes out of the peripheral area through the second area (b-area in this example), It is not located in the surrounding area for other notes (see arrow 1320).

  On the other hand, in the example shown in FIG. 14, the two musical notes 1400 and 1410 are arranged adjacent to each other and their peripheral areas overlap. In this example, the first region 1402 of the note 1400 partially overlaps the second region 1411 of the note 1410, and the second region 1401 partially overlaps the first region 1412 and the second region of the note 1410. It overlaps with the region 1411. In such a case, if the performer's finger moves along the line 1420, the first region 1402 of the note 1400 and the second region 1401 of the note 1400 (from Specifically, the first region 1412 of the note 1410 is reached through the b− region and the b + region). In the present embodiment, the following processing is executed in consideration of the case where the performer's finger is outside the peripheral area of a certain note and positioned within the peripheral area of another note. To do.

  If it is determined Yes in step 1003, the CPU 21 executes a sound generation process based on the type of the new surrounding area for other notes (step 1004). In step 1004, the CPU 21 generates a note-on event including pitch and timbre information corresponding to the peripheral area for other notes and outputs it to the sound source unit 26. Next, the CPU 21 determines whether or not the start flag STF is “1” (step 1005). When it is determined Yes in step 1005, the CPU 21 executes a guide determination process (step 1006).

  When it is determined No in step 1003, the CPU 21 sets the sound generation status in the RAM 23 to “mute” (step 1007).

  FIG. 15 is a diagram illustrating an example in which a plurality of musical notes are arranged on the staff in the image on the screen of the display unit. Lines 1420 and 1510 in FIG. 15 indicate the movement trajectory of the performer's finger. In FIG. 15, a line 1420 is newly turned on in the first region (a region) 1402 for the note 1400, passes through the b− region and the b + region of the second region 1401, and the first region of the other note 1410. This indicates that the area (area a) 1412 has been reached. In this case, C4 (first region of the note 1400), B3 (b-region of the note 1400), C # 4 (b + region of the note 1400), E4 (first region of the note 1410) in this order. Music sound is produced.

  In FIG. 15, a line 1510 is newly turned on in the first region (a region) 1402 of the note 1400, passes through the b-region of the second region 1401, and then the second 1514 of another note 1410. This indicates that the first region 1412 of another note 1410 has been reached through the b-region of the region 1411. In this case, C4 (first range of note 1400), B3 (b-region of note 1400), E ♭ 4 (b-region of note 1410), E4 (first region of note 1410) in this order. The sound is pronounced.

  In the present embodiment, when the peripheral area of a plurality of notes overlaps when the touch panel 13 is newly turned on, the note that precedes in time in the music (that is, the note located on the left side of the score) ) Is prioritized to identify the surrounding area. That is, as shown in FIG. 15, in the case of new ON, the peripheral area of the note 1400 located on the left side (see reference numerals 1401 and 1402) is changed to the peripheral area of the note 1410 located on the right side (see reference numerals 1411 and 1412). Judged in preference to. However, once the player's finger is kept on and moved into the peripheral area of another note, the peripheral area of the other note has priority.

  FIG. 16 is a diagram showing a state where the trajectory of the performer's finger has moved to the peripheral area of another note. The player's finger moves in the same manner as the reference numeral 1420 in FIG. 15 from the peripheral area of the note 1400 (actually, the second area 1401) to the peripheral area of the note 1410 (actually, the first area). 1412) (see reference numeral 1601), the peripheral area of the note 1410 has priority over the peripheral area of the note 1400. That is, when the performer's finger moves along the line 1420 and moves to the position 1601, the peripheral area of the note 1410 is given priority in a portion where the peripheral area of the note 1410 and the peripheral area of the note 1400 overlap. Therefore, as shown in FIG. 16, the sound generated by the movement of the player's finger after the position 1601 is a musical tone (E4, E ♭ 4 below the semitone, F4) on a semitone.

  Similarly, when the performer's finger moves along the line 1510 and reaches the position 1602, the peripheral region of the note 1410 is given priority in a portion where the peripheral region of the note 1410 and the peripheral region of the note 1400 overlap.

  Next, the guide determination process according to the present embodiment will be described. FIG. 17 is a flowchart illustrating an example of the guide determination process according to the present embodiment. As shown in FIG. 17, the CPU 21 determines whether the sound generation flag ONF is “1” (step 1701). The sound generation flag ONF is a flag that is set according to whether the record of the read music data is a note-on event or a note-off event in the guide processing described later (steps 1905 to 1905 in FIG. 19). 1909). If it is determined No in step 1701, the guide determination process ends. If it is determined Yes in step 1701, the CPU 21 determines whether the performance mode is the first automatic performance mode (MODE = 1) (step 1702).

  If YES in step 1702, that is, if the performance mode is the first automatic performance mode, the CPU 21 stores the pitch KEY of the note touched on the touch panel by the performer and the song data stored in the RAM 23. It is determined whether or not the pitch NOTE matches (step 1703). If it is determined No in step 1703, the CPU 21 sets “1” to the error flag ERRF (KEY) for the pitch KEY in the RAM 23 (step 1709).

  When it is determined Yes in step 1703, the CPU 21 determines whether or not the error flag ERRF (KEY) for the pitch KEY in the RAM 23 is “1” (step 1704). If YES is determined in step 1604, the error flag ERRF (KEY) is reset to “0” (step 1705).

  The CPU 21 sets the key operation flag KEYF to “1” (step 1706). Further, the CPU 21 deletes the cursor indicating the currently played note (note to be touched by the performer) in the score displayed on the screen of the display unit 12 (step 1707). Note that the note-on event in the song data of the currently playing note is stored in the RAM 23 as DATA. Therefore, the CPU 21 can specify a note by referring to DATA in the RAM 23. The DATA in the RAM 23 will be described in the guide process. Thereafter, the CPU 21 resets the sound generation flag ONF to “0” (step 1708).

  Next, the case where No is determined in step 1702 will be described. Even if it is determined No in step 1702, the CPU 21 determines whether the pitch KEY of the note touched by the performer on the touch panel matches the pitch NOTE of the song data stored in the RAM 23. Is determined (step 1710). When it is determined No in step 1710, the guide determination process is terminated. If it is determined YES in step 1710, the process proceeds to step 1707.

  When the panel operation detection process (step 303) ends, the CPU 21 executes a guide process (step 304). 18 and 19 are flowcharts illustrating an example of the guide processing according to the present embodiment. As shown in FIG. 18, the CPU 21 determines whether or not the start flag STF in the RAM 23 is “1” (step 1801). If it is determined No in step 1801, the guide process ends. If YES is determined in step 1801, it is determined whether the sound generation flag ONF is “1” (step 1802).

  If it is determined No in step 1802, the CPU 21 refers to the timer value counted by the timer interrupt process and determines whether a predetermined minimum unit time has elapsed. If it is determined No in step 1803, the guide process is terminated.

  On the other hand, if it is determined Yes in step 1803, the CPU 21 decrements the register value T of the timer (step 1804). Thereafter, the CPU 21 determines whether or not the timer register value T is greater than “0” (step 1805), and if it is determined Yes in step 1805, the guide process is terminated. If NO in step 1805, that is, if the timer register value is “0” or less, the process proceeds to step 1809. Step 1809 will be described later.

  If YES in step 1802, that is, if it is determined that the sound generation flag ONF is “1”, the CPU 21 determines whether or not the performance mode is the first automatic performance mode (MODE = 1) (step 1806). ). If YES is determined in step 1806, it is determined whether the key operation flag KEYF is “1” (step 1807). If it is determined No in step 1807, the guide process is terminated. If it is determined Yes in step 1807, the CPU 21 resets the key operation flag KEYF to “0” (step 1808).

  When it is determined No in step 1806 or after step 1808 is executed, the CPU 21 determines whether or not the error flag ERRF () is “0” (step 1809). If it is determined No in step 1809, the guide process ends. If it is determined Yes in step 1809, the CPU 21 increments the parameter AD indicating the address (step 1810) and determines whether the music data G (AD) exists (step 1811). If it is determined No in step 1811, the CPU 21 resets the start flag STF to “0” (step 1812) and stops the timer interrupt (step 1813).

  If it is determined Yes in step 1811, the CPU 21 reads the music data G (AD) indicated by the address AD and stores it as the value DATA in the RAM 23 (step 1901). Next, the CPU 21 determines whether DATA in the RAM 23 is an event (note-on event or note-off event) (step 1902). When it is determined No in step 1902, that is, when the time is stored in DATA, the CPU 21 stores the value of DATA in the register value T of the timer (step 1903).

  If it is determined Yes in step 1902, the CPU 21 stores the pitch included in DATA in the RAM 23 as pitch information NOTE (step 1904). Next, the CPU 21 determines whether DATA is a note-on event (step 1905). When it is determined Yes in step 1905, the CPU 21 specifies a note in the score displayed on the screen of the display unit 12 corresponding to DATA (note on event), and moves the cursor pointing to the note. It is displayed (step 1906). Further, the CPU 21 sets the sound generation flag to “1” (step 1907). After step 1907, the process proceeds to step 1806.

  If NO is determined in step 1905, that is, if DATA is a note-off event, the CPU 21 displays the score displayed on the screen of the display unit 12 corresponding to DATA (note-off event). The note inside is specified, and the cursor pointing to the note is deleted (step 1909). After step 1909, the process proceeds to step 1810.

  When the guide process (step 304) ends, the sound source sound generation process is executed in the sound source unit 26 (step 305). In the sound source sound generation process, when the sound source unit 26 receives a note-on event from the CPU 21, based on the pitch and tone color information included in the note-on event, waveform data of a predetermined tone color from the ROM 22 at a speed according to the tone pitch. Read out and generate predetermined musical tone data. Further, when the sound source unit 26 receives a note-off event from the CPU 21, the tone of tone and pitch indicated by the note-off event are muted.

  When the sound source sound generation process (step 305) ends, the CPU 21 executes an image update process (step 306). FIG. 20 is a flowchart illustrating an example of the image update process according to the present embodiment.

  As shown in FIG. 20, the CPU 21 detects the operation state of the touch panel by the performer (step 2001). If the player's finger is not in contact with the touch panel (“OFF” in step 2001), the image update process ends. If the performer's finger is in contact with the touch panel ("ON" in step 2001), the CPU 21 determines whether the position touched by the performer with the finger corresponds to the peripheral area of the note displayed on the screen. (Step 2002). If it is determined YES in step 2002, the CPU 21 matches the pitch of the note in which the performer's finger is located in the surrounding area with the pitch in the record specified by the parameter DAD indicating the address. Is determined (step 2003).

  When it is determined No in step 2002 or step 2003, the score update process ends. If “Yes” is determined in step 2003, it means that the player's finger is touching the peripheral area of the last note (the newest note in time) in the score arranged on the screen of the display unit. To do. Therefore, if it is determined Yes in step 2003, the CPU 21 reads a predetermined number of records of music data after the parameter indicated by the address DAD (step 2004).

  The CPU 21 generates note data including a note position and a note type based on the note-on event and the next time in the read music data record (step 2005). Also, rest data based on the note-off event and the next time is also generated in step 2005.

  Next, the CPU 21 generates image data in which notes and rests according to the note data and rest data generated in step 1605 are arranged in the staff (step 2006). Further, the CPU 21 stores the position information (coordinates) of each note and rest in the image in the RAM 23 (step 2007). Further, the CPU 21 stores the address (for example, final address) of the record of the music data corresponding to the note and rest displayed on the screen of the display unit 12 in the RAM 23 as the address DAD (step 2008).

  When the score update process (step 306) is completed, the CPU 21 performs other processes (step 307) and returns to step 302. Other processing includes reading data from the memory card via the external I / F 28, writing data to the memory card, and data transmission / reception with other devices via the external network.

  In the present embodiment, when the performance mode is the first automatic performance mode (MODE = 1), in the image displayed on the screen of the display unit 12, in the peripheral area of the note indicated by the cursor. Automatic performance will not proceed unless the performer's finger touches it. That is, since “1” is set to the error flag ERRF (KEY) in the guide determination process (step 1709), the next record of the song data is not read in the guide process (No in step 1809).

  FIGS. 21A and 21B are diagrams showing examples of musical scores displayed on the screen of the display unit. FIG. 21A shows that the player should touch the peripheral area (reference numeral 2102) of the note 2101 with the finger in the score of the image 2100. In the present embodiment, the peripheral area of the note may or may not be displayed on the image. When the peripheral area is displayed, the first area and the second area may be displayed, respectively, or only the second area that defines the outline of the peripheral area may be displayed. In the image 2100, the cursor 2103 points to the musical note 2101. This indicates that the player should touch the note 2101 (and its vicinity).

  Also, under the first automatic performance mode, the cursor remains in that position until the performer's finger touches the peripheral area of the note 2101, and the automatic performance does not proceed. On the other hand, under the second automatic performance mode, the time specified for the note 2101 (the time corresponding to the quarter note) elapses regardless of whether or not the performer's finger touches the peripheral area of the note 2101. Then, automatic performance proceeds.

  FIG. 21B shows that the player should touch the peripheral area (reference numeral 21025) of the note 2104 with the finger in the score of the image 2110. Under the first performance mode, as described above, when the performer's finger touches the peripheral area of the note 2101, an image as shown in FIG. Under the second performance mode, when the time specified for the note 2101 (time corresponding to a quarter note) elapses, the image shifts to an image as shown in FIG.

  According to the present embodiment, the CPU 21 compares the position of each note in the score displayed on the screen of the display unit 12 with the contact position by the performer on the touch panel 13, and the contact position is It is determined whether it is in the peripheral area including the position of any note. If the contact position is in the peripheral area, a note-on event based on the pitch of the note is generated, and the sound source unit 26 Output. As a result, the tone generator 26 generates musical tone data having a predetermined pitch. As described above, according to the present embodiment, the performer can generate musical sounds corresponding to the musical notes constituting the music piece by touching the musical notes on the display screen or the peripheral area thereof. Therefore, it is possible to generate a musical tone directly from the score display without having to interpret the notation.

  Further, in the present embodiment, the CPU 21 is configured so that the sound constituting the musical piece is based on the musical piece data including at least the pitch information of the note and the time information indicating the sounding timing so as to correspond to the musical note constituting the musical piece. The music is advanced by controlling the note-on event so that the high musical tones are sounded sequentially. Therefore, an automatic performance can be realized with an apparatus that generates a musical tone by touching the periphery of a note displayed on the screen of the display unit 12 described above.

  In the present embodiment, under the first automatic performance mode, the CPU 21 advances the music based on the music data when the contact position by the performer is the peripheral area of the note corresponding to the musical sound to be generated. It is configured to let you. Therefore, the music player can advance the music piece by touching (around) the correct note to be pronounced in the music piece.

  In the present embodiment, the CPU 21 displays a cursor in the score indicating the musical note corresponding to the musical tone that should be pronounced in the musical composition based on the musical composition data. Therefore, the performer can easily know which note (around) should be touched.

  Further, according to the present embodiment, the peripheral area has the first area including the musical notes and the second area located around the second area, and the CPU 21 is the contact position by the player. Is in the first region or the second region of the note position, and the pitch of the musical sound is determined based on the region to which the contact position belongs. This makes it possible to change the pitch based on the proximity between the contact position and the note by the performer.

  Furthermore, the second region includes an upper region (b + region) located above the note and a lower region (b− region) located below the note in the direction perpendicular to the staff on which the note is arranged. . When the contact position by the performer is within the first area, the CPU 21 determines the pitch of the musical sound to be generated as the pitch corresponding to the pitch of the note, and when it is in the upper area. , It is determined that the pitch is higher than the pitch of the note by a predetermined amount (for example, a pitch that is higher by a half tone). ).

  Next, a second embodiment of the present invention will be described. In the first embodiment, as shown in FIG. 10, the first area (a area) within a predetermined first radius range (see reference numeral 1001) from the position where the note 1000 is arranged, A range (see reference numeral 1002) within a predetermined second radius (> first radius) is defined as a second region (b region). Furthermore, in the second area (b area), an area whose Y coordinate is smaller than the Y coordinate of the note position is a b-area (see reference numeral 1003), and the Y coordinate is the Y coordinate of the note position. The region as described above is defined as a b + region (see reference numeral 1003).

  In the first embodiment, when the performer's finger is in the first area (area a), a musical tone having a pitch corresponding to a note is generated. When the performer's finger is in the b-region, a musical tone having a pitch that is a semitone below the pitch corresponding to the note is generated, and when the performer's finger is in the b + region, A tone that is a semitone above the corresponding pitch is produced.

  Also in the second embodiment, the first region and the second region (b− region and b + region) are provided around the note 2200, but the shape of the first region is the same as in the first embodiment. The form is different. FIG. 22A is a diagram illustrating an example of a peripheral region according to the second embodiment. As shown in FIG. 22A, in this example, the major axis of the first region 2201 is equal to the diameter of the second region 2202, and therefore, the first region 2201 and the second region 2202 at the left and right ends. Are in contact (see reference numerals 2205 and 2206).

  Similarly to the first embodiment, in the second area, an area whose Y coordinate is smaller than the Y coordinate of the note position is a b-area (see reference numeral 2203), and the Y coordinate is A region that is equal to or greater than the Y coordinate of the note position is defined as a b + region (see reference numeral 2204).

  Also in the second embodiment, when the performer's finger is in the first area (area a) (see reference numeral 2201), a musical tone having a pitch corresponding to a note is generated. When the performer's finger is in the b-region (see reference numeral 2203), a musical tone having a pitch that is a semitone below the pitch corresponding to the note is generated, and the performer's finger is in the b + region (reference numeral 2204). In the case of (see), a musical tone having a pitch that is a semitone above the pitch corresponding to the note is generated.

  Also, the change in pitch when the performer's finger moves around the surrounding area while touching the screen of the touch panel 13 is the same as in the first embodiment (see FIGS. 8 to 10). .

  In the second embodiment, the first region and the second region are in contact at the left and right ends. Therefore, the performer's finger does not move directly from the b− region of a certain note to the b + region or from the b + region of a certain note to the b− region. Therefore, as the user's finger moves, the pitch that is pronounced changes directly from one semitone above the actual note pitch to one semitone below, or from one semitone below the semitone above the actual note pitch. There is no big pitch change that changes directly.

  Next, a third embodiment of the present invention will be described. FIG. 22B is a diagram illustrating an example of a peripheral region according to the third embodiment. As shown in FIG. 22B, in the third embodiment, a third area (see reference numeral 2213) is provided between the first area (refer to reference numeral 2211) and the second area (refer to reference numeral 2212). (The radius of the first region <the radius of the third region <the radius of the second region). Similarly to the second region, the third region also has a c− region (see reference numeral 2216) and a c + region (see reference numeral 2217) according to whether the Y coordinate is smaller or larger than the Y coordinate where the note is located. Including.

  In the third embodiment, musical tones having the following pitches are generated corresponding to the areas.

  When the performer's finger is in the region a (see reference numeral 2211), a musical tone having a pitch corresponding to the note is generated.

  If the performer's finger is in the b-region (see reference numeral 2214), a musical tone having a pitch that is a semitone below the pitch corresponding to the note is generated, and the performer's finger is in the b + region (see reference numeral 2215). In the case of, a musical tone having a pitch that is a semitone above the pitch corresponding to the note is generated.

  When the performer's finger is in the c-region (see reference numeral 2216), a musical tone having a pitch that is ¼ lower than the pitch corresponding to the note is generated, and the performer's finger is in the c + region (reference sign 2217), a musical tone that is 1/4 sound higher than the pitch corresponding to the note is generated.

  In the third embodiment as well, the change in pitch when the performer's finger moves around the surrounding area while touching the screen of the touch panel 13 is the same as in the first embodiment. Yes (see FIGS. 8 to 10).

  In the third embodiment, a finer pitch change can be realized based on the movement of the performer's finger.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.

  For example, in the first embodiment and the second embodiment, as the peripheral region, a first region (a region) and a second region (b + region and b− region) are provided, and the first region ( A predetermined pitch based on the pitch of the displayed note is associated with each of the a region), b + region, and b− region. However, the present invention is not limited to this, and only the first region (a region) is provided as a peripheral region, and when the performer's finger contacts the first region, a musical tone having a pitch corresponding to the note is generated. You may comprise as follows.

  In the present embodiment, note pitches and pitches, and rests of a predetermined length are included based on song data including note-on events, times, note-off events, and time records. Music score data is generated, and a musical score in which notes and rest symbols are arranged at predetermined positions on the screen of the display unit 12 is displayed. However, the present invention is not limited to this, and musical score data including a record indicating a note, a sound length, and a rest type is stored in the flash memory 24 separately from the music data, and the CPU 21 reads the musical score data. A musical score in which notes and rest symbols are arranged at predetermined positions on the screen of the display unit 12 may be displayed.

  Further, in the first embodiment, the player's finger touches the peripheral area (the first peripheral area or the second peripheral area) of the note to be sounded under the first automatic performance mode. The music is configured to progress, but is not limited to this, and the music is configured to progress only when the player's finger touches the first peripheral area in the peripheral area. You may do it.

  In the embodiment, under the automatic performance mode, a cursor indicating the note to be touched by the performer is displayed on the screen of the display unit 12. However, the present invention is not limited to this, and other forms of note indicators may be used. FIGS. 23A and 23B are diagrams showing examples of a score displayed on the screen of the display unit in another embodiment of the present invention. FIG. 23A shows that the player should touch the peripheral area (reference numeral 2302) of the note 2301 with the finger in the score of the image 2100. In this example, the CPU 21 displays a mark (circular mark in this example) indicating the outline of the peripheral area of the note 2301 to be touched with a finger on the score as a note indicator.

  As in the first embodiment, under the first automatic performance mode, the circular note indicator remains in that position until the performer's finger touches the peripheral area of the note 2301, and Automatic performance does not progress. On the other hand, under the second automatic performance mode, the time specified for the note 2301 (the time corresponding to the quarter note) elapses regardless of whether the performer's finger touches the peripheral area of the note 2301 or not. Then, automatic performance proceeds.

  FIG. 23B shows that the player should touch the peripheral area (reference numeral 2312) of the note 2311 with the finger in the score of the image 2310. The CPU 21 displays a mark (circular mark in this example) indicating the outline of the peripheral area of the note 2311 to be touched with a finger on the score as a note indicator. Under the first performance mode, as described above, when the performer's finger touches the peripheral area of the note 2301, an image as shown in FIG. Under the second performance mode, when the time specified for the note 2301 (the time corresponding to a quarter note) elapses, the image shifts to an image as shown in FIG.

  As described above, according to another embodiment of the present invention, the note indicator corresponds to the peripheral area, so that it is possible to inform the player of the note to be touched by the finger and the area to be touched.
